Authorities responded to calls from residents in the towns of Chrzanów, Libiąż and Żarki, who reported damage to their homes.

A senior member of the firefighters in the Małopolskie region - where the earthquake happened - told Polish Radio's IAR news service that they received 13 calls so far.

There were no reports of injuries. Currently, firefighters are investigating the extent of damage to buildings.

In the village Żarki, two families were evacuated from their homes because of serious defects in the construction of their home.

A collapse in a mine in Libiąż likely caused the tremor.

Strongest earthquake this year recorded for Groningen, Netherlands

An earthquake measuring 3.1 on the Richter scale hit parts of Groningen province just after 20.00 on Wednesday evening. The epicentre was some 20 kilometres east of the city of Groningen.

The strongest quake ever to hit the region measured 3.6 on the Richter scale and was in 2012.

The quakes are caused by the ground settling following the extraction of natural gas from under the province. The government has been forced to screw back production because of the quakes, which have damaged thousands of homes.

Last month a court in Assen ruled that gas extraction company NAM must compensate home owners for the loss of value to their homes because of the earthquakes, whether or not they are up for sale.

A magnitude 5.5 earthquake shook Abepura, Indonesia at 23:20 UTC. The tremor reached 1078 km to Papua New Guinea, which has experienced several tremors already.

Both Indonesia and Papua New Guinea are on "Green Alert," this means people are unlikely to have been injured and there was little to no damage. This area is prone to earthquakes because they are on the boundary of the Australia-Pacific plate, which experiences a great deal of seismic activity. However, the many tremors that have impacted Indonesia and Papua New Guinea have caused landslides and other secondary hazards. This can cause not only loss of lives but a loss in the economy of these countries.

A major earthquake was reported by the United States Geological Survey (USGS) on Sept. 28, 2015, following a series of tremors in South America. Today's seismic activity so far has produced a 5.4 magnitude earthquake, 32 miles northwest of San Antonio de Los Cobres, Argentina. During the last 10 days, the adjoining countries of Argentina and Chile have experienced tremors measuring between 5.4 and 6.6 on the Richter Scale. Also, this morning, Honduras, which is approximately 3900 miles north of Argentina experienced 5.1 magnitude tremor, only 30 minutes earlier.

The seismic activity occurred on the Nazca plate region, which includes the offshore plate that has been jolting Chile's coastal city, Coquimbo, for the past several weeks. The largest tremor measured an 8.3 on the Richter Scale Sept. 17, 2015. CNN reported one million people were evacuated before this earthquake, which also put the region on a tsunami watch, as far away as New Zealand, over 6,000 miles from the epicenter.

Earth moved 140cms (4 feet and 7.12 inches) after Chile earthquake: Scientists

Satellite images show earth displaced by 140cm after the 16 September quake in Chile
The Earth was displaced by 140cms after a massive 8.3 earthquake rocked Chile's north coast on September 16, according to satellite images taken before and after the temblor, which were analysed by scientists, using a technique — called Synthetic Radar Aperture Interferometry (InSAR) .

This technique combines before and after satellite images into colorful maps — called interferograms.

The rainbow-colored fringes, which can be similarly interpreted as the elevation contours on a map, help scientists approximate how far the ground moved on a fault following an earthquake. The European Space Union launched the spacecraft that took these images, called Sentinel-1, in the Spring of 2014. It orbits about 430 miles above Earth and uses radar to sense ground movements.
